Please explain. What type of health insurance are you referring to? Why do you believe it has reduced your tax refund by half?
Health insurance premiums paid is only entered on a federal tax return as an itemized deduction on Schedule A. If you do not have enough itemized deductions then you receive the Standard Deduction for your filing status.
Or did you have health care insurance through one of the state Marketplace Exchanges or through helathcare.gov and received a Form 1095-A.
